Microsoft Windows Server 2016 50 User CAL

A User CAL is assigned to a specific user — that person can connect to the server from any number of devices. A Device CAL is assigned to a specific device — any number of users can use that device to connect to the server. A User CAL is the better choice when employees use multiple devices such as a laptop, tablet, and smartphone. A Device CAL is more cost-effective when one device is shared by many employees, for example on shift workstations or kiosks.

No. CAL licenses grant access to all Windows Server systems within your organization, not just one specific server. One 50 User CAL package allows 50 users to connect to any number of Windows Server 2016 servers, as well as earlier versions, in your infrastructure. You do not need to buy separate CALs for each server.

No. CAL licenses are backward compatible, but not forward compatible. Windows Server 2016 CALs allow access to version 2016 servers and earlier versions such as 2012 R2, 2012, and 2008 R2. If you plan to upgrade to Windows Server 2019 or 2022, you will need newer CAL licenses. This should be considered when planning your infrastructure migration.

Using Windows Server without the appropriate number of CAL licenses is a breach of Microsoft licensing terms. During a licensing audit, this may result in financial penalties, the immediate need to purchase missing licenses at retail prices, and a negative impact on your company’s reputation. Microsoft licensing audits are becoming increasingly common across Europe, so it is worth securing compliance in advance.

For the User CAL model, count all users who will ever connect to Windows Server — including on-site employees, remote staff, contractors, and external collaborators. Each person needs one User CAL, regardless of the number of devices they use. Remember to include occasional users as well — if they sign in to the server even once a month, they need a CAL license.

Yes, a User CAL can be reassigned to another user, but not more frequently than once every 90 days. The exception is when an employee leaves the company — in that case, the license can be transferred immediately. Reassignment only requires updating the allocation in the server licensing management tool. There is no need to contact Microsoft.
